With Monroe (Silas Weir Mitchell) and Rosalie (Bree Turner) off on their well-deserved honeymoon, another problem arises in Portland. Read on for more "Grimm" season 4 spoilers!

As a "side effect" of the potion that helped Nick (David Giuntoli) get his powers back, Juliette found herself becoming exactly like her mortal enemy. The question is will she tell her Grimm boyfriend that she's a Hexenbiest or will she try to get rid of her witchy urges on her own?

Based on her suspicious actions in last Friday's episode, "Dead Do Us," it looks like she will be hiding her new powers from Nick as much as she possibly can.

Bitsie Tulloch, who plays Juliette in the NBC show, told Zap2It in past "Grimm" season 4 spoilers that turning into a Wesen is "the last thing in the world she wants."

With her go-to couple for her Wesen-related questions still enjoying their honeymoon, the feisty redhead is "obviously going to try to hide it from [Nick] while she figures out how to correct it. She's obviously going to try to desperately get back to normal."

However, being a detective as well as a Grimm, Nick would most likely catch on to Juliette's secret soon.

Asking for help from Captain Sean Renard (Sasha Roiz), she meets up with a mysterious Hexenbiest who will supposedly help her with her little Wesen-related problem.

Will her decision to secretly ask Renard for help be the best choice or will she be thrown into more danger?

Meanwhile, another one of Renard's royal relatives will reportedly be joining the cast in Portland.

The actor that played Prince William in the "William & Kate" TV movie will be meddling with the "Grimm" royal issues, according to Christian Post.

Nico Evers-Swindell will be playing Prince Kenneth, a "handsome, ruthless and commanding" character, sent by the King to recover his grandchild, Adalind's daughter Diana.

"Grimm" airs every Friday, 9 PM on NBC.
